Lucy Kennemore b 1867

In the 1880 Census of Greene County, Arkansas Mark Walls is married to a Sarah age 50 b. GA. she has a child in the household Lucy Kennemoure it looks like. I am trying to find out which Kennemoure Sarah was married to. On the same page there is a Jackson Kennemoure and his sibblings. Anyone have any information on this family.
